Show HN: I made a digital circuit drawing and simulation game https://bit.ly/4gsUe5m

Show HN: I made a digital circuit drawing and simulation game Inspired by games like Turing Complete/Virtual Circuit Board/Logic World, I tried to make a mix of aseprite and wiredworld/wired-logic, the idea being the user can build a digital circuit using a "fullstack" pixelart creation workflow. The circuit is just an image. The primitives are (i) connected wires which have undefined, 0 or 1 state during simulation (displayed brighter or darker in function of the state) and (ii) NANDs, which are little pixel triangles. During simulation the user can interact with any wire by clicking on it, toggling its state, which is cool for messing around when learning. The simulation uses a unit-delay event driven algorithm. Then, on top of that there are little wire interfaces on the left side of the image that communicate with an external system. This external system is defined in lua and is simulated together with the main circuit (they alternate until convergence). By default there's a sandbox mode with a clock and a power-on-reset signal. The user can choose other "levels", where the API change and there are some problems to solve, from finding if a number is multiple of 3 to solving hanoi tower to finding if a number is prime. The idea is that if the user want to learn but not sure what to do they can try to solve these puzzles, or they can change the lua scripts to add their own stuff/interface for a custom project. I've also included a small wiki (circuitopedia) with some basic digital concepts to guide those who are new or are a bit rusty. It's not super detailed but I guess it can at the very least present the concepts so the user can dig further on more serious material if they want to. I developed the game in C with raylib, with scripting in lua/luajit. I've put the game on steam (for windows) and released the source code on github under GPLv3. There's also a web demo version on itch.io, even though it's a bit laggy: https://bit.ly/3ZwrAds... . Feedback is appreciated! https://bit.ly/3XI0izF September 14, 2024 at 11:43PM

Show HN: Search San Francisco using natural language https://bit.ly/3TqDMc5

Show HN: Search San Francisco using natural language Hey HN! We're Alex and Szymon from Bluesight ( https://bit.ly/3TQumqH ), where we're developing a foundation model for satellite data. We've created a demo to showcase the current capabilities of state-of-the-art models and identify areas for improvement. Our demo allows you to search for objects in San Francisco using natural language. You can look for things like Tesla cars, dry patches, boats, and more. Key features: - Search using text or by selecting an object from the image as a source ("aim" icon) - Toggle between object search (default) and tile search ("big" toggle, useful when contextual information matters, like tennis courts) - Adjust results with downvotes (useful when results are water images) - Click on tiles to locate them on a map - Control the number of retrieved tiles with a slider We use OpenAI's CLIP model ( https://bit.ly/3ZnyIZL ) to put texts and images into the same embedding space. We do a similarity search within this space using text query or source image. We are using CLIP finetuned on pairs of satellite images and OpenStreetMap ( https://bit.ly/3TsY8Bg ) tags ( https://bit.ly/3ZipzSh ) because vanilla clip performs poorly on satellite data. We pre-segment objects using Meta's Segment Anything Model ( https://bit.ly/3ZqkMy6 ) and pre-compute CLIP embeddings for each object. We'd love to hear your thoughts! What worked well for you? Where did it fail? What features do you wish it had? Any real-world problems you think this could help with? https://bit.ly/3z5wCmM September 12, 2024 at 06:06PM

Show HN: Interested in an automated fact checking service? https://bit.ly/3XhbS3a

Show HN: Interested in an automated fact checking service? Hey everyone, I'm working on an automated fact checking service that works like so: 1. Paste a link to the website, X or facebook comment you want to fact check, 2. Select a quote on the site, 3. We search for relevant results from research databases, reputable news sites and searches on the web, 4. You get a web page with the quote, fact check rating, summary of the findings and sources, 5. Share that fact check back to the source, so people can be aware of the relevant information. This is a work in progress (currently a landing page) and I'd love to know if you are interested in it (it's worth me continuing to work on). Would love to hear your opinions or ideas :) https://bit.ly/3TtnizM September 13, 2024 at 07:46AM

Show HN: I built an AI-powered app that helped me lose 30 lbs and gain muscle Hey everyone, Like many of you, I've been amazed by the latest AI advancements and have integrated AI into my daily life. As a fitness enthusiast, I was searching for an all-in-one tool that could track my nutrition, workouts, and sleep in one place, while providing insights into how these factors correlate with each other. This need led me to create HealthMaxAI. Using the app, I've personally lost over 30 pounds of fat, which has been incredibly motivating. HealthMaxAI has truly transformed my approach to health and fitness, and I believe it can do the same for others. I'm excited to share this tool with you and would love any feedback you might have. Your insights will be invaluable in making HealthMaxAI even better. Thank you in advance for your time and for checking out the app! https://bit.ly/3TOqpTp September 12, 2024 at 12:06AM

Show HN: Forms with OpenPGP https://bit.ly/3MDgbRA

Show HN: Forms with OpenPGP I'm Pal, the creator of an open source form/survey platform. It's written in Rust and Svelte and it's all on GitHub: https://bit.ly/3AThjxO . My aim is to do something similar to how Proton encrypted emails: keep it simple and user-friendly, so that basically everyone can switch to it from Google/Typeform. Of course, there's some compromises. You can't really do integrations, since the server doesn't have the raw responses to send anywhere. But there's still tons of use cases where Palform's features suffice. The encryption is powered by the amazing Sequoia PGP library and simply uses OpenPGP. I know it's not a perfect protocol, but it's been around for ages and audited several times. Users need to be able to trust Palform, and a DIY obscure cryptographic system would make that hard. Plus, this way you can import + export your keys and everything stays interoperable. It even has webhooks, so your servers can store PGP keys and you can decrypt the form responses yourself. https://bit.ly/3ZfFmRR September 10, 2024 at 11:53PM

Show HN: Semantic Bookmark Manager Hi Hacker News, I would like to share my new side project: the Semantic Bookmark Manager. This web application is designed to help users manage and semantically search for their bookmarks using the RAG technique. Traditional bookmark managers can become quite disorganized and difficult to navigate as they grow. This tool offers a solution by eliminating the need for manual categorization, therefore simplifying the overall user experience. It is open-source under MIT license Thank you for your attention, and I hope you find it useful :) https://bit.ly/4gi8ZId September 11, 2024 at 12:27AM

Show HN: Fire for the Wall – A Guide to Censorship-Resistant Tools and Networks Hi HN, I've been working on a project called "Fire For The Wall", which is an ongoing and maintained guide to help people resist internet censorship. It covers censorship-resistant tools, protocols, and networks, as well as how censorship firewalls like the GFW (Great Firewall) work. The guide is organized into the following sections: - Censorship Circumvention Tools - Censorship Circumvention Protocols - Censorship-Resistant Networks - Censorship Techniques - Censorship Analysis Tools Each document provides details on how these tools work, what privacy/security precautions to take, and how to set them up. The project is open-source and under the CC BY-NC 4.0 license, meaning it's free to use and modify with proper credit. I'm looking for contributors who are interested in helping expand and refine this guide. Whether it's improving documentation, adding new tools, or helping with analysis, all contributions are welcome! If you're interested, please read the contribution guidelines before starting. Thanks for checking it out, and I'd love to hear any feedback or suggestions! Guide: https://bit.ly/4dXp5VZ Repo: https://bit.ly/3MFPKdY https://bit.ly/3MFPKdY September 10, 2024 at 11:31AM
